First, lighter corn lodging, no support, the plant's own ability to adjust, with the growth of plants, they will naturally stand upright; for serious lodging, can wait until the ground after the rain is a little dry, using artificial methods to straighten Plants. The first and second internodes of the base of the corn stem are relatively fragile. In addition, some of the roots have been damaged. To prevent breakage and increase the root injury during erection, it is best to operate together. One of them grabs the upper part of the corn plant and pulls it up. Another person cultivates earth in the root; for broken lands, the broken plants must be removed from the field as soon as possible to avoid rot and affect normal plant growth.
Second, timely supplement fertilizer, lodging of corn due to poor photosynthesis, physiological function disturbance, affecting growth and development. For a field that only weighs once, you can chase it once more. If the top dressing is not applied with P and K fertilizers, phosphorus and potash fertilizers should be used. Mushi diammonium phosphate and potassium chloride should be 5 kg each. The first topdressing fertilizer has been applied with P and K fertilizers. It should be combined with big bell mouth fertilizer, Mushi. Urea 15 to 20 kg, in order to facilitate the increase in production.
Third, pay attention to the prevention and treatment of diseases and insect pests, corn lodging is more prone to disease, pay attention to inspection. For leaf diseases, 70% thiophanate-methyl 800-fold, 50% carbendazim 500-fold, or 75% chlorothalonil 300-fold can be sprayed, once every 7-10 days, and even spray 2 ~3 times
Some other farmers have asked whether they can destroy Chinese cabbage, green onions or radishes. To be sure, it is not feasible to do so. Once a maize plant is not confirmed, it cannot be saved. It should not be abandoned. It is decided that the deforestation is blind, and corrective measures should be taken actively.
